Have a Ceed 3 SW CRDi, only done 500 miles so far but it appears to have averaged about 45mpg so far, happy with that, about the same as the Focus C-Max 1.6 TDCi it replaced and it will get better as the miles pile on. The claimed for the Focus was 58mpg combined against 60mpg for the Ceed thus expect the Ceedto be doing about 2mpg more than the Focus, will report back later.
The other car in the house is a 2008 BMW 118d, the one with stop-start, claimed is about 63mpg. Had it for 19000 miles now and it has averaged 47.5mpg. Way short of the claimed figure but I still think its good for a 2 litre with 143bhp, much better than a 2002 Mondeo with 128bhp I had some years ago, that only managed to average about 39 mpg against a claimed 48mpg.
Manufacturers "massage" the figures I am sure to make the cars look as good as possible on paper, I use the figures as a guide only when buying. The upside is thelower the claimed consumption the lower the CO and the less tax we pay each year, the BMW is 119 CO's thus £30 per year.
Only ever owned one car that nearly matched the climed figures, a 2005 Mini Cooper S, combined was about 33 mpg, over 15000 miles it did about 32 mpg, way better than I expected.
All the above figures are based on fuel used not on the sometimes inaccurate computer, 90's G o l f was always 8 mpg higher than reality.
One solution would be for an independant organisation like NCAP to carry out the tests rather than allowing the manufacturers to carry them out but how would they garantee getting a "standard" spec car for testing?
Personally I am happy with the current situation, if the figures were made more realistic we would all end up paying more car tax.
On the motorway I too would expect to be get 60 ish from a CRDi Rio, if you are getting a lot less there is clearly something wrong with your car. Has the dealer flashed the ECU, even if the car has the latest software its going to do no harm and may help, surely worth a try.
Best car I have ever had for economy was a 96 G o l f TDi, 90 bhp. Would average 60 mpg on a trip to Scotland and about 50 around town regardless of driving style. When you think that a current Ceed is 113 bhp and weighs a considerable amount more the figures that we are getting are not really that bad. Add to that the fact that the G o l f terrified following cars with the huge cloud of smoke it kicked out when you floored it shows that we have come a long way with diesels.
One other factor that is rarely considered is the accuracy of the odometer. The door to door trip to Scotland was exactly 400 miles in the G o l f. In both the Mundaneo and C-Max that followed it the trip was 380 miles, exactly the same route, a 5% difference. If that is factored into the mpg figures the 60 mpg the G o l f acheived drops to 57 mpg, exactly the same as the C-Max regulary acheivedon the same trip.
Will have to wait until May to find out how far it is to Scotland in the Ceed but by then the car should have loosened nicely and I should get a good mpg comparison. Fingers crossed until then.
